A mixture of tetrahydro-2H-pyran-4-amine (130 mg, 1.285 mmol), 4-(5-chloro-2-fluoropyridin-3-yl)-N,N-bis(4-methoxybenzyl)-6-methyl-1,3,5-triazin-2-amine (345 mg, 0.719 mmol), and cesium carbonate (165 mg, 0.506 mmol) in THF (2.5 mL) was heated under microwave irradiation (100° C., 15 min; 120° C., 2×15 min). The mixture was partitioned between EtOAc (10 mL) and water (5 mL). The organic layer was washed with water, saturated NH4Cl, dried over Na2SO4 and concentrated. The resulting solid was triturated with hot MeOH (10 mL) to give a yellow solid (300 mg). LCMS (ES, pos.): calcd for C30H33ClN6O3: 560.2; found: 561.2 (M+H)+. 1H NMR (400 MHz, CDCl3) δ 9.48 (d, J=7.24 Hz, 1H); 8.67 (d, J=2.54 Hz, 1H); 8.13 (d, J=2.54 Hz, 1H); 7.18 (t, J=9.10 Hz, 4H); 6.87 (d, J=8.61 Hz, 4H); 4.82 (s, 2H); 4.77 (s, 2H); 4.17-4.29 (m, 1H); 3.91 (dt, J=11.74, 3.62 Hz, 2H); 3.81 (s, 3H); 3.80 (s, 3H); 3.55 (td, J=11.25, 1.96 Hz, 2H); 2.52 (s, 3H); 1.96 (br. s., 2H); 1.33-1.48 (m, 2H).
